21 Jan 20 SEO Tips for 2010 – Tip 4
Dynamic URL’s – If pages are dynamically created, try to remove or rewrite as many parameters in the URL as possible or use URL / Mod rewrite.
- Any time you have session data or query string parameters in a URL, you are decreasing the possibility of indexation. Particularly if there are conventions such as ?PID=23D-55.aspx trailing along, when a SEO friendly naming convention could have taken its place with a bit of programming. You can rewrite entire segments, sub folders, categories, etc. without losing functionality or compromising SEO value.
